Generally, Y-90 are imaged by bremsstrahlung SPECT. However, the images demonstrate a low quality. Thus, we considered using a Compton camera. 30 MBq of Y-90 was encapsulated in a glass bottle. The bottle was set at the center of a water filled NEMA phantom.  A Si/CdTe Compton camera was set under the bottle and the distance was 10 cm. Then the bremsstrahlung X-ray was measured for six hours. We found that the image quality depended on the energy window of the Compton camera. The Y-90 source was clearly imaged with 300-400 keV energy window and the spatial resolution was highest.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"第111回日本医学物理学会学術大会","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"酒井, 真理"}],"nameIdentifiers":[{"nameIdentifier":"654188","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菅井, 裕之"}],"nameIdentifiers":[{"nameIdentifier":"654189","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菊地, 美貴子"}],"nameIdentifiers":[{"nameIdentifier":"654190","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鳥飼, 幸太"}],"nameIdentifiers":[{"nameIdentifier":"654191","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"荒川, 和夫"}],"nameIdentifiers":[{"nameIdentifier":"654192","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山口, 充孝"}],"nameIdentifiers":[{"nameIdentifier":"654193","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長尾, 悠人"}],"nameIdentifiers":[{"nameIdentifier":"654194","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河地, 有木"}],"nameIdentifiers":[{"nameIdentifier":"654195","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小高, 裕和"}],"nameIdentifiers":[{"nameIdentifier":"654196","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"国分, 紀秀"}],"nameIdentifiers":[{"nameIdentifier":"654197","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"武田, 伸一郎"}],"nameIdentifiers":[{"nameIdentifier":"654198","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 伸"}],"nameIdentifiers":[{"nameIdentifier":"654199","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋, 忠幸"}],"nameIdentifiers":[{"nameIdentifier":"654200","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"取越, 正巳"}],"nameIdentifiers":[{"nameIdentifier":"654201","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中野, 隆史"}],"nameIdentifiers":[{"nameIdentifier":"654202","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"荒川 和夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654203","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山口 充孝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654204","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"長尾 悠人","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654205","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河地 有木","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654206","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Y-90 Bremsstrahlung Imaging using Compton Camera","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Y-90 Bremsstrahlung Imaging using Compton Camera"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-06"},"publish_date":"2017-11-06","publish_status":"0","recid":"66507","relation_version_is_last":true,"title":["Y-90 Bremsstrahlung Imaging using Compton Camera"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:48:11.855505+00:00"}
